DISPENSER FOR SELF-ADHESIVE TAPE Filed Dec. 28, 1950 INVENTOR ATTORN EY Patented June 2, 1953 DISPENSER FOR SELF-ADHESIVE TAPE Harry Donkin, Ealing, London, England, assignor to Reno] Products of Canada Limited,

Toronto, Canada Application December 26, 1950', Seriai No. 203,103 In Great Britain November 21, 1950 The subject matter of this invention is a one piece plastic dispenser of the type adapted to utilize a pressure sensitive roll tape. One object of the invention i realized in the provision of an effective andsimplified dispenser of the character referred to wherein the shell thereof has one upstanding side only and this wall embodies a peripheral transversely arranged inwardly overhanging and rearwardly and downwardly flared rim characterizing in part a top wall of the shell and in part an advantageous back rest for the palm of the hand. of the operator using the dispenser, the back rest being merged with a transversely arranged bottom wall of the shell extending from the side wall and adapted when the dispenser is used to be conveniently seated on the middle fingers of the hand of the operator or on an appropriate sup porting surface when the dispenser is not in use.

Specifically another object resides in arranging the overhanging rim to the rear of a disc shaped part of the unitary and upstanding side wall which carries a centrally arranged tubular portion comprising a resilient and normally retracted finger having a radially but outwardly extending locking lip or terminal adapted to be actuated by the roll of tape when moved into or out of the shell and concomitantly on or 011 the tubular portion. Another object is predicated upon serviceable and efiective means for anchoring tape unwound from the roll on an upwardly portion inw-ardly overhanging the front inclined. wall of the shell, the front wall being merged. with the unitar upstanding side wall and with the bottom wall or base of the shell, thus precluding buckling of the side wall. Other important objects and functional and structural features advantages of the invention will appear from the following detailed description considered in the light of the accompanying drawings wherein.

Fig. 7 is a sectional view on the line 'I---!: of Fig. 2.

According to the invention, the dispenser is in the form of a one piece open plastic shelL'genorally designated having the bottom substantially rectilinear wall 2, constituting a base for the shell and adapted to be seated on a suitable supporting surface SF; The side wall t is integral or merged with bottom wall 2 and isv disposed at a right angular relation or normal thereto. The front inclined. wall 3 is integral or merged with bottom wall 2 and side wall t and is disposed at right angles or normal thereto. Tubular portion 5 has its inner'end merged with side wall. 5 and has a free unsupported outer and E spaced from bottom wall 2 and disposed to the rear of reentrant gap R dividing side- Wall I into front and. rear components FL and RC respectively (Figs. 1, 2 and 3).

Tubular portion 5 as shown is cylindrical and is arranged substantially centrally, of the rear component BC, the forward portion of the lat-.

ter may be considered for purposes of specifics tapered and in part constitutes the top wall TW and in part the rear wall or back rest BR of. the plastic shell SH. Ofcourse rim F is integral or merged with base 2. and the side wall I.

As illustrated spaced slits l interrupt the body of the tubular portion 5 and leadv to the free unsroported outer end E. Lip or terminal 9 ex;- tends radially outwardly, that is, laterally of the resilientfinger or member 8 straddled by slits 1. Lip 9 removably holds the roll of. tape TP on the tubularportion 5 contiguous to side wall If as is well understood. lhe upwardly flared portion or ledge FF at the upper end of the front inciined wall 3 of shell SH embodies an anterior toothed face TF and a posterior flat face FF of constitutes a rest for the palm of the hand of the operator when holding the dispenser.

More specifically, the inclined wall 3, the bottom wall or base 2 and the transversely arranged peripheral rim F constitute a fully open side face of the shell and this open side face extends the entire length and height of the shell and is opposite to the upstanding side wall I. Through this open side face it is apparent that the roll of tape I? can be readily and promptly inserted into or removed from the shell and concomitantly on or off the tubular portion 5 at which time the roll actuates or abuts lip 9 flexing the resilient member inwardly to release or unlock the roll, that is, resilient member or finger 8 is normally flush with tubular portion 5. In other words finger 8 is held normally retracted to be flush with tubular portion 5. Of course by manually pressing lip 9 inwardly, the reel or roll of tape can be quickly slipped or mounted over tubular portion 5. Also due to the inherent operation of the resilient finger 8 the roll may be placed over lip 9 to automatically press finger 8 in- 'wardly prior to shifting the roll over tubular portion 5. In either case after the roll is completely seated on and about tubular portion 5, the resilient finger 8 snaps back or retracts automatically. This operation is inherent. In addition if the roll of tape be on tubular portion 5, this roll of tape if desired may also be conveniently employed to automatically actuate to depress finger 8. In this connection, the roll or reel is first manually grasped by the fingers of the operator, who thereafter simply pulls the roll towards lip 9 and the latter is depressed as the roll is pulled off tubular portion 5. This function is likewise inherent in the structural organization herein specifically described and shown.

It should be observed that top wall 'I'W progressively increases in width in proportion to its distance away from the disc shaped portion D. Roll of tape TP is preferably of the pressure "sensitive or self adhesive type and an end therewith base 2 and unitary upstanding side wall I,

thus precluded buckling of the latter relative to base 2. Similarly back rest BR serves a like function in that it interconnects side wall i and base 2. While the above is a description of the principles of this invention in connection with the specific dispenser illustrated, it is to be clearly understood that this description in the light of such illustrations is made only by way of example and not as a limitation on the scope of the invention as defined in the accompanying claims.
